Bridge Priority
Bridge priority is used in determining the root switch, root port and designated port. The
switch with the highest priority (lowest numeric value) becomes the STP root switch. If all
switches have the same priority, the switch with the lowest MAC address will then become
the root switch. Select a value from the drop-down list box.
The lower the numeric value you assign, the higher the priority for this bridge.
Bridge Priority determines the root bridge, which in turn determines Hello Time, Max Age
and Forwarding Delay.
Hello Time
This is the time interval in seconds between BPDU (Bridge Protocol Data Units)
configuration message generations by the root switch. The allowed range is 1 to 10
seconds.
